A nalysis of Books. [J uly, 
by the contact of the pyrolusite present in the ironstone of 
Mount Morgan, with hydrochloric acid from the decomposition 
of chlorides. The siliceous sinter, containing in some cases as 
much as io ozs. 14 dwts. gold per ton, gives evidence of former 
geyser acftion. The hot spring is supposed to have originated 
subsequently to the formation of the desert sandstone. 
The author thinks this discovery important, not merely from 
the large quantity of gold actually found, but as indicating that 
palaeozoic reefs rich in gold extend under the cretaceous rocks in 
the western interior of Queensland.

all Classes and Young Naturalists. Vol. I., No. 2, June,

Nature.” “ Philately,” however, which is a newly coined word 
for the collecting of postage-stamps, is quite outside our scope. 
Our Corner. Vol. V., No. 6, June 1, 1885. 
“ Work for the Microscope,” by Mr. J. Horner, is a sound, 
plainly written introduction to the use of this important instru- 
ment of research, and will doubtless guide not a few persons to 
its intelligent employment. 
“The Heretic at Burlington House,” by W. Greatheed, — a 
somewhile contributor to the “ Mason College Magazine,” — 
seemed the possible title of irreverent criticisms on the learned 
societies established in that far western locality ; but we find it 
a survey of the Exhibition at the Royal Academy, and as such
